Definitions
- the invention relates to a machine according to the preamble of claim 1.
- Machines of this type are primarily intended for grinding the teeth of circular saw blades, but they are also fundamentally suitable for machining band and gang saw blades, as well as milling cutters and the like, and machining can also be carried out by electrical discharge machining using one or more rotating eroding discs occur. Accordingly, the present invention is not limited to grinding the teeth of circular saw blades.
- the intended machining position is generally the one in which the tip of the cutting tooth to be machined lies on the axis of the machine defined as the pivot axis.
- the tooth tip is a sharp edge in which a tooth face (rake face) intersects with a tooth back (open face).
- a certain distance can be specified for a large number of workpieces to be machined one after the other, by which the workpiece slide is shifted from its loading position into a position in which the feed device can engage in a tooth space in order to push the adjacent tooth face into its desired position, in which the probe device can precisely measure the distance from the workpiece holder, ie the radius of a circular saw, by scanning the associated tooth tip.
- the invention has for its object to design a machine for machining workpieces with cutting teeth, in particular circular saw blades, that the machine workpieces that differ greatly in their relevant dimensions, fed in any order without pre-orientation and still be processed fully automatically can.
- the design of the feeler device according to the invention ensures that the foremost cutting tooth in the direction of movement of the workpiece carriage from its loading position to the swivel axis of the machine, even if its tooth tip is not oriented towards the swivel axis, triggers a signal as soon as the tooth tip of this cutting tooth reaches the barrier. In this way, a first dimension identifying the workpiece is obtained. NEN, since the numerical control knows the respective position of the workpiece carriage and the location of the barrier. The thus obtained on the workpiece first measured value deviates usually from actually relevant measure of the workpiece in a circle ⁇ saw blade by its diameter, still too much off as that on ⁇ reason this first measure already with a sophisticated machining the workpiece be started could.
- the S ize can be determined by simple means, once the feed device in a known per se manner has acted and has brought a tooth face in the desired position in which they in the pivot axis the machine contained ⁇ Tenden plane. It does not need the tooth ⁇ breast of the same cutting tooth to act, the tip is scanned nally ur ⁇ .
- the scanning of the tooth tip of that cutting tooth whose tooth face is brought by the feed device in the desired position can Schehen ge ⁇ by different means.
- One possibility is that the Tasteinrich ⁇ tung, with which the first measurement has been performed, is then used again to determine the required correction to the measured value for ⁇ sprün Republic.
- the sensing device In order to fulfill this task, the sensing device must however complicated ge ⁇ be staltet than is priced for the extraction of only the first measurement ⁇ required.
- a correction device separate from the scanning device be provided for the renewed scanning of the workpiece and for the delivery of correction signals.
- ⁇ is self-generating part of the correcting means.
- Neute scanning of the workpiece is therefore for example, to the machine uses existing grinding or eroding wheels.
- This can in turn in different ways serve ignalgeber than S, for example, characterized in that vibrations are measured, which occur when the workpiece is touched by the tool, while the latter is rotated.
- the gate of the first sensing device there are several ⁇ re design options.
- it can be a light barrier of a known type. But as in generic Ma ⁇ machines in a more or less wide area of the work ⁇ must be zeugs expected risk of contamination, it is generally preferable to provide a barrier in the form of a body ⁇ handy barrier that moves only when needed in a touch position each but assumes a protected rest position during each workpiece machining.
- FIG. 1 shows an oblique view of a numerically controlled machine according to the invention for grinding saw blades
- FIG. 2 shows an enlarged detail from FIG. 1, with a slightly changed viewing direction, in a setting for tooth back grinding
- FIG. 4 shows a plan view of a touch device of the machine, Fig.5 successive working positions of the machine to 8 in partial views similar to Fig.3, and
- FIG. 9 shows a view of the machine corresponding to FIG. 3 in equipment and setting for tooth face grinding.
- a circular saw with carbide-tipped cutting teeth 12 is shown, each of which is to be ground on its tooth face 14 and on its tooth back 16, while its tooth tip 18 precisely maintains a predetermined position.
- the machine shown has a machine frame 20 on which an elongated guide body 22 is mounted so as to be pivotable about a horizontal pivot axis A in the example shown.
- the pivot axis A is defined as the line of intersection of a vertical first reference plane B and a horizontal second reference plane C.
- a stroke axis D extends along the guide body 22, which intersects the pivot axis A at a right angle and represents the axis of movement of a reciprocating carriage 24.
- a spindle axis E which intersects the stroke axis D at a right angle and extends in the normal position shown at a right angle to the pivot axis A, a tool slide 26 is guided on the stroke slide 24.
- the tool slide 26 can be inclined in both directions about the lifting axis D from its normal position shown. In the event that among the cutting teeth 12 to be machined are those whose tooth face 14 or tooth back 16 does not extend, as shown, parallel to the pivot axis A, the tool slide 26 is corresponding to the slope of the tooth face 14 to be machined or the tooth back 16 the stroke axis D is inclined.
- the tool spindle 28 is mounted in a bearing housing 32, which is held on the tool slide 26 in an electrically insulated manner by means of an insulating sleeve 34 and is connected to a power source 38 via an electrical line 36.
- Example stationary horizontal workpiece carriage ⁇ guide which extends at a right angle to the pivot axis A.
- a workpiece 42 displaceable carriage part support a plant 44 supports ⁇ .
- the workpiece holder 44 includes a mandrel which defines an axis of rotation F, parallel to the pivot axis A, for the workpiece 10; on this mandrel the work ⁇ piece 10 is placed centrally.
- the workpiece carriage 42 is to take to edit the cutting teeth 12 an operating position shown in Fig.l to 3, 8 and 9, wherein the about the rotational ⁇ axis F whipped circle on which the tooth tips 18 of the ⁇ tee plant are 1 0, the pivot axis A cuts.
- the workpiece 10 can thus be rotated step by step into machining positions, in each of which a tooth tip 18 lies on the pivot axis A.
- the tooth tip 18 of the to be machined Cutting tooth 12 is arranged at a point H in which the pivot axis A penetrates the central plane G.
- the Klemmein ⁇ direction is substantially conventional in the art, however, has the particularity that one of the clamping jaws 46 is connected by an elec ⁇ trical line 48 to the power source 38, so that an electrical circuit closes when the W ork ⁇ tee 10 is touched by the tool 30.
- a feed device 50 with a rod 52 which is controlled along a feed axis I is extendible and carries at its end a feed head 54th A feed head 54, a cross slide 56 is slidably guided parallel to the pivot axis A and carries a feed finger 58.
- the Q uerschlitten 56 normally occupies a rest position in which the feed finger is arranged away from the center plane 58 is G ⁇ ; only when a feed movement is to be executed, the Q is uerschlitten 56 parallel to the pivot axis A to a position moved in which the feed finger 58 gaps in the tooth ⁇ before the next to be processed cutting tooth 12 is immersed ⁇ and then by extension of the rod 52 against the Tooth ⁇ breast 14 presses this cutting tooth and pushes it into the position described, in which the tooth tip 18 coincides with the point H ⁇ .
- the feeding device 50 is controlled so that it repeats this process with the next successive cutting tooth 12 so that only the finally stops in the said position, and is then machined, after the workpiece 10 between the jaws 46 firmly ⁇ has been clamped. It is possible that the feed finger 58 is not immediately engaged by switching on the feed device 50 in a tooth gap of the workpiece 10, because when on ⁇ insert the workpiece 10 and is not ensured during the subsequent feeding of the workpiece carriage 42, that the tooth tip 18 of the first cutting tooth 12 to be machined is already in the second reference plane C. However, to ensure this ultimately, the following measures are envisaged:
- the machine includes the one shown in FIG. 4, which has a scanning slide 62 which, by means of a hydraulic or pneumatic piston-cylinder unit 64, runs along a linear guide 66 parallel to the pivot axis A, that is to say normal to the central plane G, between a rest position and that shown in FIG Touch position can be moved back and forth.
- a barrier 70 is mounted on the scanning slide 62 by means of a joint 68; the joint 68 defines an axis of rotation K, which is parallel to the central plane G and to the first reference plane B, and thus is perpendicular in the example shown.
- the barrier 70 extends parallel to the first reference plane B, is located in front of it at a distance X and, measured in the central plane G, has a length L which is greater than the largest tooth pitch T of the workpieces 10 to be machined. 5 conditions provide guarantee that the forward movement of the workpiece carriage 42 is interrupted with a workpiece 10 placed on its workpiece holder 44 when the most forward-pointing tooth tip 18 is at a distance X from the second reference plane C.
- the key slide 62 carries a switch 72, in the example shown an electro-inductive limit switch, to which a fixed stop 74 is assigned.
- the workpiece carriage 42 like the lifting carriage 24 and the tool carriage 26, is numerically controlled and can only be started after a workpiece 10 to be machined has been placed on the workpiece holder 44 when the switch 72 has reported that the probe carriage 62 has been extended, the barrier 70 has therefore reached its key position shown in FIG.
- the barrier 70 is normally held in its illustrated position parallel to the first reference plane B by a spring 76, but is pivoted about the axis of rotation K by bumping a tooth tip 18 and actuates a switch contact 78 assigned to it, which outputs a signal to the numerical control 80 of the machine.
- the forward movement of the workpiece carriage 42 is interrupted, and then the piston-cylinder unit 64 is actuated, so that the probe carriage 62 together with the barrier 70 is retracted into the rest position of the probe device 60.
- the path for the workpiece 10 is free and the workpiece carriage 42 is moved further by the distance X, so that the tooth tip 18, which had hit the barrier 70, reaches the first reference plane B according to FIG dependent, more or less far above or below the second reference plane C, that is not yet at the intersection H, is arranged.
- the feed device 50 is actuated in the manner described and thus ultimately achieved that a tooth tip 18 lies in the second reference plane C.
- the tooth tip 18 has not remained in the first reference plane B but has exceeded it by a small amount Z, which is however not tolerable for machining, which is caused by renewed scanning of the tooth tip 18 is to be determined and corrected.
- the tool 30 which can be driven in rotation is used, in the example shown the cup-shaped or plate-shaped grinding wheel.
- the tool 30 is electrically conductive and is therefore able to close a circuit via the electrical lines 36 and 48 and the current source 38.
- the tool 30 for scanning is not driven at its normal operating speed, which is usually in the order of 3000 to 5000 rpm during grinding, but at a speed of, for example, 50 to 300 rpm. min, in the order of magnitude between 1% and 10% of the operating speed.
- the tool 30 is driven by an electric motor 84, which is fed in a known manner via a frequency converter.
- the small one intended for scanning Speed is sufficient to throw cutting emulsion, dirt and the like. From the tool 30 and also ensures that slight wobbling and crumbling of the tool 30 have no influence on the scanning accuracy.
- the tool 30 is thus advanced by means of the tool carriage 26 until the tool lightly touches the tooth tip 18 facing it and consequently closes the circuit fed by the power source 38 via the workpiece 10.
- the measurement process described is repeated, so that a decisive radius or diameter of the workpiece 10 is determined for both types of teeth.
- the principle of scanning an electrically conductive workpiece 10 by means of a likewise electrically conductive tool 30 can be used for various types of measurements.
- a plate-shaped grinding wheel provided as a tool 30 can scan the tooth gap depth of the workpiece 10 during a numerically controlled movement of the lifting slide 24 and can also control the position of the tooth face 14 by infeed of the tool slide 26. If it is feared that inaccuracies in the positio ⁇ discrimination of the workpiece 10. This results in that the work piece ⁇ slide back and forth in the manner described 42 is reciprocated, the distance X may be less than shown dimensioned ⁇ the. This has the consequence that in accordance with FIGS.
- the amount + Z can be in a manner corresponding to the amount - (Fig. 3) Z determined by scanning with the tool 30 in its capacity as egg ⁇ part of a measuring and correcting device 82 and correct.
